CONDENSER.

Specification of Letters Patent.

Patented April 21, 1908.

To all whom it may concern:

tain. new and useful Improvement in Con- I densers, of which the following is a true and exact description, reference bein had to the accom anying drawings, which iorm a part thereo My invention relates to condensers in which a vacuum is normally maintained in the condenser body by means of an air pump and is especially ap licable to cases where the water intake into t e condenser body is situated at a level above that of the water supply, the object of my invention being to rovide means whereby under such conditions there will always be a sullicient quantity of water available to maintain the condenser in proper operation and my invention consists in providing in the conduit between the water su ply and the water intake of the condenser, t ie water supply tank having a part or extension at a greater height above the Water supply than that to which the water can be drawn by suction or vacuum, this upper part of the tankbcing connected with the air ump and a non-return valve being situsited in the imiakc passage from the tank to the condenser.

The nature and details of my invention will be best understood as described in connection with the drawing in which they are illusof the tank C, carries the ell'ective height of the tank above the level of thirty feet from the surface of the water supply, that is,

to a greater height than the water can be drawn by suction or vacuunn .The condenser body E, is of usual form,

and the condensin apparatus, as a whole, of

the general type, own as the Weiss countor-current condenser, as described, for instance, in the reissued patent to Weiss No. 11591 dated 2nd March 1897. An annular water chamber E. receives the water from the intake conduit 1), and showers it through the usual internal mechanism in the steam s ace of the condenser. The lower art of tie condenser body connects with t is barometric column indicated at E while the upper part communicates with the pipe or conduit E the end E, of which projects down into the enlar ed end G, of the barometric pipe G. Both the stand ipes E and G open into a water reservoir in icated at H, and from the up e1 art of the enlarged conduit portion G ear s the ipe I, which connects it with the air ump The gate valve L, is rovidedlor c o'sing the opening of the pipe into the chamber G, and in the rear of this valve a conduit K, connects thevair pump pipe I, with the upper end (1 ,01 the tank. F, indicates the pipe through which the exhaust steam is led to the condenser.

in starting in improved condenser the gate valve ll isc osed and the air pump set in operation, exhausting the air from the tank 0, with the result that the water is drawn up into it through the pipe B, and until the water level in the tank and its extension a proximates thirty feet from the surface oi the water supply A. Whilethe tank is filling the non-return valve 0 will of course remain closed, or if there is any difliculty with the proper closure of this valve at the beginning of the operation, the intake passage 1), can be positively closed i through the valve 1). As soon as the tank i C, is charged with Water, the valve L, and, if it has been closed, the valve D, also, are

opened: the air pump is then in direct com- Ky-F- into the intake of the condenser which then {100 assumes its normal mode of operation, the

proper vacuum being maintained in the tank to insure its being always approximately filled so that any temporary interruption in thevacuum in the condenser will not result in the cutting oil of the water supply, ample reserve of water being always present in the tank to make any more temporary fall ineffective as affecting the Waterfsupply.

Having now described my invention, what 110 I claim as new and desire to secure by Letters Patent is 1. In combination With acondenser having an air pump connected to the head of the condenser body and a Water supply situated at a lower level than the condenser intake, a Water supply tank situated above the Water intake of the condenser and connected thereto and to the water supply, a non-return valve located in the connection from the tank to the intake, said valve being arranged to close when the vacuum in the condenser body is broken and a conduit leading from the air pump connection to the top of the tank.

2. In combination with a condenser having an air pump connected to the head of the condenser body and a Water supply situated at a lower level than the condenser intake, a

water supply tank situated above the water intake of the condenser and connected thereto and to the Water supply, a non-return valve located in the connection from the tank to the intake, said valve being arsemesranged to close when the vacuum in the condenser body is broken, a conduit leading from the air pump connection to the top of the tank and a normally 0 en valve whereby the connection between t e condenser body and air pump can be closed at will.

3. In combination with a condenser having an air pump connected to the head of the condenser body and a Water supply situated at a lower level than the condenser intake, a Water supply tank situated above the Water intake of the condenser and connected thereto and to the water supply, a non-return valve located in the connection from the tank to the intake, said valve being arranged to close when the vacuum in the condenser body is broken, a conduit lead ing from the air pump connection to the top of the tank and a nonneturn valve in the intake of the tank.
